| titleOfInvention | Preparation device and method for spectrum control sample |
| abstract | The invention discloses a preparation device of a spectrum control sample, which comprises a riser, a mold and a bottom plate which are sequentially arranged along the vertical direction, wherein the riser and the mold are mutually connected, the hollow parts of the riser and the mold are communicated to form an accommodating space, the bottom of the mold is connected with the bottom plate, and when liquid metal is poured from the top of the riser, the liquid metal is cooled in the accommodating space to form the spectrum control sample, wherein the inner diameter of the riser is gradually reduced along the pouring direction of the liquid metal, and the riser comprises at least two riser parts with different cone angles, so that the cooling speeds of the liquid metal in the riser are different. The preparation device for the spectrum control sample is formed by combining different materials and different structures, a temperature field favorable for sequential solidification is established from top to bottom along the pouring direction of copper liquid, and the defects of top shrinkage cavity, bottom shrinkage porosity and uneven tissue of the existing spectrum control sample can be overcome. |
